Prehistoric Animals

Prehistoric animals represent the hundreds of millions of extinct animal species that lived on Earth during the last 500 million years, before humans started recording history. Trilobites, dimetrodons, dinosaurs, sea monsters, flying reptiles, wooly mammoths are few of the well known types of prehistoric animals. Scientists known as paleontologists help discover much of the evolutionary history of life on Earth by studying fossils and prehistoric animal remains.

How did the dinosaurs grow so very large from just tiny hatchlings just 1 foot long? How did they feed such fantastic growth? Scientists turn to the dinosaur's closest living relatives - the alligator and crocodile - to find out.
